Description

Technical Field

[0001] This utility model relates to the field of backpack technology, specifically to a folding backpack. Background Technology

[0002] Backpacks, as tools for carrying everyday items, come in various types based on their materials and structures, including backpacks, shoulder bags, and crossbody bags. Backpacks, by distributing weight across both shoulders, effectively reduce the burden on one shoulder, making them more comfortable for long-term carrying. They also have a large capacity, accommodating commuting or travel essentials such as laptops, books, sunscreen, and power banks. The interior can also be designed with multiple compartments for easy organization.

[0003] For example, Chinese patent application number 202510116742.9, published on May 13, 2025, discloses a storage bag and its preparation method. The storage bag includes a first cut piece,

[0004] The second piece and adjustment structure are sewn onto the first piece to form a bag body. The bag body has a storage cavity, and a drawstring assembly is provided at the entrance of the storage cavity to tighten the bag's entrance. The adjustment structure is located on either the first or second piece and includes an adjustment buckle and a webbing. The adjustment buckle is fixed to the first end of the webbing, which loops around the outside of the bag body. The second end of the webbing is adjustablely connected to the adjustment buckle. When the bag contains clothing, pulling the second end of the webbing compresses the bag, reducing space usage; the webbing also facilitates carrying and transporting the bag. A pocket is provided on one side of the first piece. When the bag is empty, it can be folded back and stored inside the pocket for easy storage and transport.

[0005] The aforementioned literature describes a method of accommodating the backpack by adding an extra pocket on the front or back of the backpack body. However, since the pocket is located on the front or back of the backpack body, and the backpack body is located vertically, the upper and lower sides of the backpack body are prone to becoming tangled during folding, making it impossible to fold. In particular, the drawstring part at the top of the backpack body has a large volume and is prone to becoming tangled during folding. Furthermore, setting up a separate pocket body can result in low space utilization. Utility Model Content

[0006] The purpose of this utility model is to provide a foldable backpack that can be folded and stored in a storage bag located at the opening of the backpack when not in use. When using the backpack, the storage bag can be opened to restore the backpack to its original shape. At the same time, the storage bag can cover the opening of the backpack to prevent items inside from being lost.

[0007] This utility model provides the following technical solution: a folding backpack, including a bag body, the upper end of the bag body is provided with a bag opening, a pull member is provided at the bag opening, the bag opening is opened and closed by the pull member, a storage bag is provided at the upper end of the bag opening, one end of the storage bag is fixedly connected to the bag body and forms an integral part with the bag body, the outer edge of the other end of the storage bag is provided with an opening and closing device, a storage layer is formed inside the storage bag, after the bag opening is closed by the pull member, the other end of the storage bag extends from above the bag opening to the other side of the bag opening to cover the bag opening, and is detachably connected to the other side of the bag opening by a connecting device provided on the storage bag.

[0008] The above setup allows the storage bag to be opened via the opening and closing mechanism when the backpack is not in use. This simultaneously separates the storage bag from the other side of the bag opening. After removing the items from the bag, the bag is laid flat and folded from the end furthest from the storage bag towards the end closest to it, ensuring the folded bag matches the size of the storage bag. The opened storage bag then wraps around the folded bag, and the opening and closing mechanism closes the folded bag, storing it inside. Because the storage bag has a pull tab near the bag opening, the pull tab can be closed first, followed by the folding of the remaining parts, thus ensuring the entire backpack is stored inside the storage bag without any obstruction. In case of confusion, when using the backpack, open the storage bag using the opening and closing mechanism to restore the bag body. You can then put items into the bag from the opening. Then, close the opening using the pull tab, allowing the storage bag to extend from one side of the opening to the other. The storage bag is detachably connected to the bag body via a connecting device on the storage bag, ensuring that the storage bag completely covers the closed opening and fits snugly against it. This method of first closing the opening with the pull tab and then covering it with the storage bag effectively prevents items from being lost while carrying the backpack. It is highly practical, allowing the storage bag to be used as both a bag flap and a storage compartment.

[0009] Furthermore, there are two pulling members. The two pulling members pass through the opening on the outside of the bag opening and are sleeved on the outside of the bag body. After the pulling members are stretched outward in opposite directions, the bag opening forms a drawstring and is closed.

[0010] The above design allows the bag opening to be stretched to form a drawstring by the pull tab, thus preventing items inside the bag from falling out of the opening. When it is necessary to open the bag, simply pull the outer edge of the opening outwards.

[0011] Furthermore, the storage bag includes a first storage surface and a second storage surface, with a common connection point on the first and second storage surfaces. The first and second storage surfaces are connected to the bag body through the common connection point, and the storage bag is arranged to open and close around the common connection point with the bag body. The opening and closing device is located at the outer edge of the first and second storage surfaces. After the opening and closing device closes the first and second storage surfaces along the outer edge, a storage layer is formed inside the storage bag.

[0012] The above settings allow items to be stored in the storage layer when the bag is not folded.

[0013] Furthermore, both the inner surfaces of the first and second storage surfaces are provided with a waterproof layer.

[0014] With the above configuration, when the bag is folded and stored in the storage bag, the outer side of the first storage surface and the outer side of the second storage surface wrap around the folded bag. After the first and second storage surfaces are closed by the opening and closing device, the inner side of the first and second storage surfaces are exposed. The waterproof layer on the inner side of the first and second storage surfaces can prevent the stored bag from getting wet.

[0015] Furthermore, the opening and closing device is a zipper.

[0016] The above settings make opening and closing the storage bag easy.

[0017] Furthermore, the connecting device includes a first connector and a second connector. The first connector is disposed on the outer side of the second storage surface, and the second connector is disposed on the outer side of the bag body and on the other side of the bag opening. The first connector and the second connector are matched to achieve a detachable connection.

[0018] The above design allows the storage bag to be detachably connected to the bag body via the first and second connectors after it spans across and covers the bag opening.

[0019] Furthermore, the bag body is provided with shoulder straps and dividers.

[0020] The above setup allows the bag to be carried by the shoulder straps, while the compartments can be used to store items. Attached Figure Description

[0028] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0029] like Figure 1-7 As shown, this utility model provides a folding backpack, including a bag body 1 and a storage bag 4. The upper end of the bag body 1 is provided with a bag opening 2, and a pull tab 3 is provided at the bag opening 2. The bag opening 2 is opened and closed by the pull tab 3. (See reference) Figure 2 There are two pull members 3. After passing through the opening on the outside of the bag opening 2, the two pull members 3 are sleeved on the outside of the bag body 1. The pull members 3 move in opposite directions (see reference). Figure 3 After being stretched outwards in the XX direction, the bag opening 2 forms a drawstring and closes. This allows the pulling element 3 to hold the bag opening 2 closed, preventing items inside the bag from falling out. When the bag opening 2 needs to be opened, simply pull the outer edge of the opening 2 outwards. In this embodiment, the pulling element 3 is an elastic drawstring.

[0030] like Figure 1-2 As shown in Figures 4 and 7, a storage bag 4 is located on one side of the bag opening 2. One end of the storage bag 4 is fixedly connected to the bag body 1 and forms an integral part with the bag body 1. Specifically, one end of the storage bag is sewn onto the bag body 1, allowing the storage bag 4 to rotate up and down around the sewn area with the bag body to cover or open the bag opening. An opening and closing device 5 is provided at the outer edge of the other end of the storage bag 4. A storage layer is formed inside the storage bag 4. In this embodiment, the storage bag 4 includes a first storage surface 6 and a second storage surface 7. A common connection point 8 is provided on the first storage surface 6 and the second storage surface 7. The first storage surface 6 and the second storage surface 7 are connected to the bag body 1 through the common connection point 8 to form an integral part. The opening and closing device 5 is located at the outer edge of the first storage surface 6 and the second storage surface 7. After the opening and closing device 5 closes the first storage surface 6 and the second storage surface 7 along the outer edge, a storage layer is formed inside the storage bag 4. In this way, when the bag body 1 is in an unfolded state, items can be stored in the storage layer. In this embodiment, the opening and closing device 5 is a zipper.

[0031] like Figure 1 , 4 As shown in Figure 7, in this embodiment, a waterproof layer is provided on the inner side of the first storage surface 6 and the inner side of the second storage surface 7. The waterproof layer is a waterproof fabric layer, and the bag body is made of a flexible fabric layer. When the bag body 1 is folded and stored in the storage bag 4, the storage bag 4 is opened by the opening and closing device 5 to form the first storage surface 6 and the second storage surface 7. The folded bag body 1 is then wrapped by the outer side 21 of the first storage surface 6 and the outer side 22 of the second storage surface 7. After the first storage surface 6 and the second storage surface 7 are closed by the opening and closing device 5, the inner side 61 of the first storage surface 6 and the inner side 62 of the second storage surface 7 are exposed to the outside. The waterproof layer provided on the inner side 61 of the first storage surface 6 and the inner side 62 of the second storage surface 7 can prevent the stored bag body 1 from getting wet.

[0032] like Figure 2 and 7 As shown, after the bag opening 2 is closed by the pull member 3, the other end of the storage bag 4 extends from above the bag opening 2 to the other side of the bag opening 2, covering the bag opening 2. It is detachably connected to the other side of the bag opening 2 by a connecting device provided on the storage bag 4. In this way, when the bag body 1 is in an unfolded state and items are loaded inside the bag body 1, it can be ensured that the bag opening 2 is located below the second storage surface 7 in the storage bag 4 and can completely cover the drawstring opening, thereby further preventing items inside the bag body 1 from being lost from the bag opening 2.

[0033] like Figure 7 As shown, the connecting device includes a first connector 11 and a second connector 12. The first connector 11 is disposed on the outer side 22 of the second storage surface 7, and the second connector 12 is disposed on the outside of the bag body 1 and on the other side of the bag opening 2. The first connector 11 and the second connector 12 are matched to achieve a detachable connection, thereby facilitating the detachable connection between the storage bag 4 and the bag body 1 through the first connector 11 and the second connector 12 after the bag 4 spans across the bag opening 2 and covers the bag opening 2. In this embodiment, the first connector 11 is a first Velcro fastener, and the second connector 12 is a second Velcro fastener that matches the first Velcro fastener.

[0034] like Figure 1 and 2 As shown, the bag body 1 is also provided with a shoulder strap 13 and a divider layer 14. The shoulder strap 13 is used to carry the bag body 1, while the divider layer 14 can be used to place items. In this embodiment, the divider layer 14 is a bag body provided on the front of the bag body 1.

[0035] The working principle of this utility model is as follows: When the backpack is not in use, the storage bag 4 is opened through the opening and closing device 5, simultaneously disengaging the storage bag 4 from the other side of the bag opening 2. After removing the items from the bag body 1 through the bag opening 2, the bag body 1 is laid flat and folded from the end furthest from the storage bag 4 to the end closest to the storage bag 4, so that the folded bag body 1 matches the size of the storage bag 4. The outer side of the first storage surface 6 and the outer side of the second storage surface 7 formed by the opened storage bag 4 wrap around the folded bag body 1, and then the opening and closing device 5 closes the bag, storing the folded bag body 1 inside the storage bag 4; when using the backpack... When using the backpack, the storage bag 4 is opened via the opening and closing device 5 to restore the backpack body 1. Items can then be placed into the backpack body 1 through the bag opening 2. The bag opening 2 is then closed via the pull member 3, simultaneously allowing the storage bag 4 to extend from one side of the bag opening 2 to the other. The storage bag 4 is detachably connected to the backpack body 1 via a connecting device on the storage bag 4, ensuring that the storage bag 4 completely covers the closed bag opening 2 and is tightly attached to the bag opening 2. This method of first closing the bag opening 2 via the pull member 3 and then covering the closed bag opening 2 with the storage bag 4 effectively prevents items inside the backpack body 1 from being lost during use, making it highly practical.
